Arrow Check engine light and rotten egg smell *Update*

My 2006 Murano check engine light is on and there is a rotten egg smell from the exhaust sometimes. I replaced the gas cap hoping that would fix the problem because the check engine code says its an Evap code. Any ideas?

Welcome to the forum.

The Check Engine light and sulfur smell may be just a coincidence.

Bring your car to any big chain auto parts store and they will read the error codes for free. They can also let you know what the codes refer to. I suggest posting the codes here and we will do our very best to diagnose the issue.

Thanks for the welcome njjoe! I did have the error code scanned and its an EVAP error. I replaced the gas cap but it didnt help. I was wondering if the sulfur smell could be the converter going bad and also causing the engine light?

I didnt take note of that. The guy at the autoparts store looked it up and said it was an evap code which could be a few different things. gas Cap, Catylitic Converter, and a couple other items in the system. I will bring it to the dealer and see how what they think..

No dead cat! I always thought rotten egg smell was catylitic converter but I guess the dealer will figure it out

Sorry if flew over my head the first time. Makes sense. I always thought rotten egg smell meant bad Cat also but the dealer says he doubts it but wont rule it out. I cant imagine what else would cause that smell besides the Cat. I know what a rich running motor smells like and it isnt rotten eggs. Thanks for the reply!

So today the dealer tells me that the catylitic converter is bad and in addition to that they are telling me that the fuel level sensor is bad and that I need a fuel pump. The converter is covered under warranty but the fuel pump is not covered. A new fuel pump installed is $640.00....I told them to replace the converter only. I am curious to see if the check engine light goes off after the new converter is installed. Not sure I believe I need a new fuel pump!

What does a fuel level sensor have to do with all this? When did that enter the equation? Is your fuel level working correctly?

They siphoned out half of his tank, but the gauge only went down a quarter tank. Houston, we've found a moneymaker!

I think the stealership is trying to make some $$$ from me. I will admit that my gas guage has never worked properly since day one but its not something I complained to the dealer about. And again the fuel guage has been like that since the Murano was brand new and there was no check engine light as a result. I need that light off so my car will pass NYS inspection and the dealer knows this so they are trying to say I have more problems that will prevent that light from going off but I dont believe them. I think after the new Cat is installed the light will go off.

I have been reading online and see that there is a TSB for the fuel level sensor. I searched it and on edmunds there is a NHTSA ITEM NUMBER - 10022420....What does this mean in terms of a recall item? On the Nissan website its just a TSB that says to replace only the bad sensor and nothing else. The dealer wants to replace the entire fuel pump assembly. If this is not a recall item then why would there be a NHTSA number associated with it?

They are kidding, right? I'd love to know their rationale for even being in the tank.

The MO has a saddle tank. Once the total level drops to about three-quarters any attempt to siphon out more will only result in the driver-side section being emptied.

I think they are simply trying to enhance their bottom line.
